Abstract: A study was conducted to evaluate the Saccharicterpenin effects on production performance, intestinal canal micro-flora population, biochemical parmeter of blood on the piglets early weaning(PEW). Treatments were as follows: treatment Ⅰ is the control group, the group treatment Ⅱ,Ⅲ,Ⅳ,Ⅴ respectly contained 250 mg/kg Saccharicterpenin, 500 mg/kg Saccharicterpenin, 250 mg/kg Saccharicterpenin plus 4 mg/kg Flavomycin, 4 mg/kg Flavomycin. The results showed that: Supplemented with 500 mg/kg Saccharicterpenin of Flavomycin plus 250 mg/kg Saccharicterpenin, the number of TP、GLO、G/A were improved, the group treatment Ⅲ is the best; IgA is significant improved(P<0.05), the group treatment Ⅱ,Ⅲ,Ⅳ,Ⅴ was higher 43.21%, 104.89%,73.21%,27.74% than the control, IgG,the group treatment Ⅱ,Ⅲ,Ⅳ,Ⅴ was higher 10.50%,12.07%,11.05%,10.26% than the control, group; treatment Ⅱ,Ⅲ,Ⅳ,Ⅴ on the Serum of BUN was higher 2.67%,2.96%, 2.81%, 2.52% than the control, but no significant difference to GLU(P>0.05), The number of AST, ALT, ALP of the group treatment Ⅲ was higher than others, but the group treatment Ⅱ,Ⅲ,Ⅳ,Ⅴ of LDH was lower 2.71%,4.02%, 2.96%, 1.65% than the control.
